Research Progress of Thermal Conductive Materials for Lithium-ion Batteries

Abstract

The rapid development of renewable energy and batteries has increased people’s demand for lithium-ion batteries. Thermal management plays a very important role in the manufacturing of lithium-ion batteries, as overheating is an inevitable problem when batteries are used for a long time. Moreover, thermal. However, during the charging process, the battery will generate a large amount of heat. This excessive heat will cause the battery’s capacity to decrease and also pose a risk of heat runaway. It also plays a crucial role in ensuring the safety, efficiency and lifespan of the battery. This article, however, reviews the latest advancements in thermal conductive materials applied in battery thermal management systems. Using the CAS method, this study systematically analyzed the advantages and disadvantages of carbon-based and metalbased related materials, and particularly emphasized their thermal conductivity and stability. Furthermore, this article also discusses the technologies that enhance conductivity while also reducing costs, as well as the innovations related to this technology, and the future development trends of composite materials. By comparing different materials, this study ultimately concluded that although there is no single material type that can completely solve the problem of thermal management, the use of hybrid materials and new materials still holds potential for the sustainable development of lithium-ion technology.
